My first attempt was based on a pair of jumper cables the salesperson told me were 4 gauge, but are apparently 6 or 8 gauge. I can’t even run the heater at 750 watts without alarms going off. Back to the drawing board.

If I succeed, I will update this rating. At this point the project is becoming more a mistake than a solution.

Update: I ultimately had a mechanic install the unit which had a cost of $150.00. Still less than $600.00 for a new heater core. However, since Cobra chose not to publish this information upfront in their information, my review remains ***. Be very aware of installation limitations!

Update: We’re beating a dead horse here. I’m going back to my propane tent heater and giving up on the large inverter. I’ll still use a small one for computers, etc. when I travel. This is a backup vehicle, so it’s not worth a lot of repairs or upgrades. The inverter is going on eBay. I feel the product was incredibly misrepresented, and I would now only give it one star.
